[BUG] VPC Flow Integration shows many errors when trying sample data

[Swiddis]

What is the bug?
The current VPC Flow integration isn't configured correctly, when trying the sample data it reports a lot of errors.

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Start a clean instance with OSD, or clear the existing instance:

DELETE ss4o_*
DELETE _data_stream/ss4o_*
DELETE _index_template/*
DELETE _component_template/*

2. Access the VPC integration
3. Click "Try it"
4. Access the dashboard
5. See lots of errors

What is the expected behavior?
The panels of the VPC integration should not show errors. They may show "no data" if and only if the sample data does not actually supply any data matching the panel.

Able to reproduce - @wanghd89 we may need to take another look at your contribution, but I remember it was working, maybe some schema changed or something after the change went in
